Before the days of beau Calvin Harris, Taylor Swift had another leading man: her younger brother, Austin (she even used to arrive to big events with him in tow as her date). She didn't forget about her sibling yesterday when she posted an adorable Flashback Friday post on Instagram to wish Austin a happy birthday. The two are pictured inbetween takes of what seems to be a family photoshoot from the '90s (just check out Taylor's watercolor-print dress and Austin's rainbow-striped collar if you have any doubt of the decade). Taylor captioned the pic: "Thanks for 24 years of LOLs."

The sibling duo has managed to stay tight over the years despite Taylor being on tour frequently (they hang out so often that there are full articles devoted to why Tay's baby bro should be dating pal Selena Gomez). Mutual friend Jaime King also took to Instagram to wish the younger Swift a great day, sharing a photo of him holding her son Leo Thames, of whom Taylor is the godmother, captioned: "Happy Birthday...I am so...lucky that you are truly family." Here's to hoping that Austin's birthday was as sweet as all of the well wishes he received.
